Hi, sorry for the late reply. Here is the mockup for how this feature can be implemented.

 ![Mockup Spray](https://krita-artists.org/uploads/default/original/3X/1/d/1df268601ebc69d03cd65ab7f8c9774240dbe09f.jpeg)

Basically need a controller similar to size and opacity but for particles denstiy.  
I for the stroke preview I took a screenshot of the brush stroke I drew in csp for more clarity. 😆

Hmm, I hope texture setting can be implemented too but when I was testing out texture settings in csp, it might affect the look if texture is enabled.  
Since CSP have texture each stroke and each tip options, the resulting visual on the brush may be different.

Below is the comparison for each settings:

Texture each stroke

The brush stroke seems to have texture masked to it as a whole.

It seems that each particle in the brush have texture applied to it, so it looks less like spray paint on a texture surface.

Krita does not have texture each stroke implemented yet, but I have some “thoughts” about how it can be implemented in the neighbouring thread.

I was thinking that allowing this feature can show effects of spraypaint on a wall or textured paper but I have no idea about the difficulty of implementing that feature. (I hope I did not get too sidetracked, but I think it is relevant to this thread’s feature request.)

> Let me see the author of the post and you wanted something like this Brush Texture applied to every Stroke? Following the example of they given in every post, i saw the idea they looking its something similar like this? I made this a while ago. its how they works in Clip Studio Paint.

Anyways, I am not sure the complexity of this request but hopefully this can be used for future reference.

Thanks and regards  
Carina
